Abstract: PURPOSE:To obtain a shock absorber which is simple in structure, and is stable in function by providing a pump circuit which responds to excitation frequencies, for the closed circuit of working fluid, and thereby adjusting the opening area of a throttle valve using the output pressure of the pump circuit as a pilot pressure. CONSTITUTION:A plunger 28 is assembled in a pressure chamber 30 formed in the hollow structure of a piston nut 19. The plunger 28 is moved to an upper or a lower dead center as a piston 3 is displaced to the extending direction or to the pressing direction so that the pumping action permits the working fluid of a pilot chamber 40 to flow in and/or out of the pressure chamber 30. And the flow rate of oil flowing into the pressure chamber 30 is proportional to excitation frequencies, and the flow rate flowing to the pilot chamber 40 out of the pressure chamber is throttled by an orifice 43, the hydraulic pressure in the pilot chamber is thereby low in a range of low frequencies, and is increased as excitation speeds are accelerated. And when a connecting groove 22 is provided for the outer circumference of a spool 20 which is subjected to the pressure from the pilot chamber, a hydraulic shock absorber can be obtained, which is provided with attenuating force corresponding to excitation frequencies with the opening area of ports 38 and 39 changed.

Title: Washing machine
Inventor: AKAGI TAKAYOSHI
IPC: D06F17/08
Filed: 1999-10-18
Abstract: PROBLEM TO BE SOLVED: To accurately judge the load quantity to determine the appropriate water supply level even with initial dispersion in the tension of a V-belt and the change of strength caused by aging degradation. SOLUTION: When special key operation is performed in the inside empty state 6f a washing spinning tub (S1), the no-water left state is confirmed by a water level sensor (S3). A motor is driven for a short time to rotate a pulsator, and motor pulses during the inertia rotation are counted (S4). In the case of the counted value W0 being 79<W0<196, the reference value to each load quantity (water level) is computed from a specified calculation expression on the basis of W0 (S7). The calculation expression is experimentally obtained in advance so that the inclination of a curve composed including the reference value becomes steeper in proportion to the increase of the value W0. Upon confirming that there is no operational error (S8), the computed reference value is stored in an EEPROM (S9) and used as reference data for subsequent load quantity judgment.  The reference value can thereby be appropriately determined according to the state of a washing machine at that moment, so that the load quantity can be accurately judged.
